Here is another video that demonstrates the characteristic differences between cellulose insulation and fiberglass insulation.

Titled “The Big Burn” by its producers, the video is not a true scientific controlled study like the burn test videos sponsored by CIMA. However, it does a good job of demonstrating how different cellulose insulation and fiberglass insulation react and manage flames in a fire. Cellulose insulation in this demonstration clearly stops the direct high heat source from damaging the building wall members.
